Application filed September 24, 1906. Serial No. 336,939.

1'0 aZ-Z whom it may concern:

Beit known that I, PAUL OLSON, a citizen of the United States, residing at Stoughton,

in the county of Dane and State of VViscon-' have invented certain new and useful I sin, Improvements in Block-Molding Machines, of which the following is a specification.

My invention relates to improvements in what may be termed block-molding machines. Its object is to provide for greatly simplifying the construction and arrangement of the parts, to readily effect the retention in place of the mold members, to provide for molding blocks of different outlines, to perform the molding operation in a simple and expeditious manner, and to accomplish these ends with facility and expedition.

Said invention consists of certain structural features or instrumentalities substantially as hereinafter fully disclosed, and specifically pointed out by the claims.

In the accompanying drawings, illustrating the preferred embodiment of my invention, Figure 1 is an isometric perspective View thereof with certain mold-member-retaining contrivances out of effective or operative position. Fig. 2 is a like view of the device with the mold members in assembled position. Fig. 3 is a like view showing the in vention as adapted for molding beveledend ed cornerblocks. Fig. 4 is a plan view sho wing three block-molds in position upon the table. Fig. 5 is a detached side view of one of the holding-levers.

In carrying out my invention. I provide a table 1. preferably a casting, mounted upon legs 2 of preferably frame-like outline and also of metal and suitably bolted or secured to said table, said legs or frames also being braced in position by diagonally-arranged bars or braces 3, suitably secured to said table upon its under side at about the center and to the bottom cross-pieces of said legs or frames. Said table or support is equipped at suit-able intervals apart along its relatively rear portion with upstanding angled bars or members 4 4 and 5 5, with their short horizontal base portions resting fiat upon said table and having nut-equipped bolts 6 6 and 7 7 passing therethrough and through trans 'verse slots 8 8 and 9 9, respectively, formed in said table, one of said upright bars being adapted to be moved into engagement with the rear mold member for its retention in position, as seen in Fig. 2. The lateral bars or members 5 5 are themselves provided with jam-nut-equipped bent or hooked bolts 10 for loosely attaching or pivoting thereto lateral lever-arms 11, as disclosed by the draw ings, said lev er-arms being provided with adjustablependent lugs or stops 12, effective for engagement with end extensions or studs 14 of a board member 13, hinged or pivoted to the forward edge of the table 1, said leverarms also being adapted to retain the lateral mold members in position, as also seen in Fig. 2. The adjustability of the pendent lugs or stops 12 is effected by-forming a longitudinal slot 15 in each of the lever-arms 11 and employing, preferably, two nut-equipped bolts 16 for each pendent lug, applied thereto and inserted through the slot 15 of the respective lever-arm.

It is noted that the mold members, which may be of the outline or configuration herein shown, or other form, according to the shape it may be desired to impart to the contemplated building block, being suitably assembled or placed, preferably upon an offbearing plate or pallet upon the table 1, the rear uprights or members 4 5 are adjusted relatively to that side of the mold formed by said members and the board member 13 swung upward to stand vertically to and hold the forward side of the mold in position. The lever-arms 1 1 are now connected to the hooked bolts 10 andbrought into such position as to engage their lugs or pendants 12 with the end extensions or studs 14 of the board member 13, said lugs or pendants bemg requisitely adjusted to effect the clamping of all in fixed or immovable relative position and to the table. The device is now ready for the placing and tamping of the concrete or other material within the mold in effecting the block-molding operation, after which of course the parts may be readily disassembled and removed from the table and the block formation of concrete borne away upon its bed plate or pallet for drying or completion of the building-block.

In the form of the device as shown or sugbuilding-block, I hinge or articulate, as at 17, to the board member 13 an additional end section 18, in which case a supplemental end mold member a is employed, together with the primary end member of the mold, which latter is adjusted into position to abut said supplemental end member. The lever-arm 11 at that end is adjusted by shifting its I hooked bolt connection 10 to the nearer upgested in Fig. 3, as in molding a beveled right 4 and by swinging it with said upright so as to bring said lever-arm into contact with the ends of the parts a 18, the lever-arm having its lug or pendant 12 resting upon the table 1 in that event, as shown.

I claim l. A device of the character described, comprising a table or support provided with a hinged or pivoted member at one edge and adapted to be movable in a vertical plane, uprights adjustable along said table with relation to the rear mold members, and lateral lever-arms adapted to pivot upon certain of said uprights and movable verticallyand laterally relatively to the lateral mold members for engagement therewith, said lever-arms havingpendent lugs effective for the retention of said hinged member in operative position.

2. A device of the character described, comprising a table or support provided with a hinged at one edge or pivoted board member, uprights applied to said table or support, one being adapted to hold in position tion the rear mold member and two of which are equipped with pivot-forming bolts, and lateral lever-arms, adapted to engage the lateral mold members and each having one end adapted to be connected to said pivotforming bolts, and having its other end provided with a pendent lug effective for the retention of said hinged or pivoted board member in operative position,

3. A device of the character described, comprising a table or support provided at its relatively rear portion with adjustable uprights, two vof which are equipped with hooked pivot-bolts, a hinged or pivoted,

board member at one edge of said table having end extensions or studs, and lateral leverarms effective for connection with said pivotbolts and adapted to engage the lateral mold members and provided with pendent lugs adapted to engage said studs.

4. A device of the character described,-

comprising a table or support, means adj ustable thereon with relation to, and for aiding the retention in place of a mold member, a hinged board member applied to one edge of said support or table and lateral lever-arms supported in place from said adjustable means and adapted to engage the lateral mold members and having adjustable pendent lugs effective for engagement with end studs of said hinged board member.

5. A device of the character described, comprising a table or support, means for aiding the holding of the mold members in position at the rear, upon said table, a hinged board member at the forward edge of said table, a pivoted or articulated end section or member applied to said hinged board member, and lever members or arms having a pivotal or swinging movement upon said mold-holding means upon the rear of said table, and equipped with means effective for the retention of said forward-edge-hinged board in place, together with said articulated end section or member.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

PAUL OLSON.
